Analysis of A New Hybrid Multilevel Inverter Topology with Reduced Device Count

In this research work, a new hybrid MLI is proposed. The MLI is developed by combining cross-switched MLI (main circuit) with switched-capacitor MLI (auxiliary circuit). Due to interconnection of switched-capacitor circuit with the cross-switched MLI, it reduces the number of power supplies, switching devices and further boosted the input voltage. It has been observed that the proposed topology requires lesser number of switches, power supplies, and gate drivers as compared to other topologies. Fundamental switching scheme known as Half-Height (HH) is considered as the modulation scheme for the inverter due to minimum switching loss. The effectiveness and merits of the proposed topology has been proved by simulation study of a 23-level proposed MLI in MATLAB/SIMULINK platform.
